To celebrate the 5th anniversary of the popular indie game Undertale, Toby Fox had announced last week that his partnership with Fangamer, 8-4, and MUSIC Engine would feature a live-streamed concert of the original Undertale soundtrack. The concert was available to watch on the official Youtube channel and Twitter account (and still is for those that missed the opportunity).

The concert, which is a pre-recording of an orchestral concert done by MUSIC Engine in Tokyo last year, brought all fans of the title together for three and a half hours to listen to their favorite songs years after their original release. All of the songs (from all of the possible Undertale routes) were included in the musical performance in the order they appear in the game and on other music streaming sites (with the exception of fan-favorite song Megalovania saved for the very last performance).

me: I have to make a song for my game I will make it in 20 minutes using free samples I downloaded online
orchestra: (arranges and does an amazing performance of it in front of 50000 people)
me: cool

Even with it being organized by Fangamer and 8-4, the end of the concert featured some (pre-recorded) original piano music done by Toby Fox himself. As he admitted to composing the music for this very event, he also told fans that the music composed of various arrangements from Deltarune, along with other songs from the original game soundtrack.

Thanks for listening to my messy piano playing at the end too. The first piece was an arrangement of a song from DELTARUNE, the last two were UNDERTALE songs with improvisations. The middle one especially (Snowdin arrangement) I just randomly made up for the concert

Along with this announcement, Toby Fox also tweeted that he would be designing and selling new Undertale themed merchandise. Although these highly anticipated designs do not have an official release date from him or the official Undertale website, they are available for pre-order as of now. He also mentioned that pre-existing Undertale merchandise would also be restocking soon as well (even though there is not a set date for that), with the proceeds going towards COVID-19 centered charities and relief funds.

Second, smaller announcement.

I designed a shirt! Only the back is shown here, but the not-yet-revealed front was drawn by me! The proceeds will go to charity, so please feel confident buying my weird drawings.

This, and more, will be shown on https://t.co/CiqBCnPvlA on 9/15! pic.twitter.com/tCHCCmsPZ1

Since it’s release in 2015 Undertale has been a hit with fans, critics, and streamers alike who fell in love with the intricate (multiple) storylines, unforgettable characters, and catchy soundtrack. Currently, Undertale is available to play on PC, Nintendo Switch, and PS4, with its still in progress sequel Deltarune being available for the same platforms. However, as Deltarune is being released by chapters instead of all at once, only the first episode is available to play (even though Fox keeps fans updated on the progress for episode two on the official website).
